ZERO EMISSION VEHICLES AUSTRALIA
8-16 CELL LITHIUM BATTERY MANAGEMENT SYSTEM
BMS min temp
-41C to 100C The minimum allowable temperature for
the battery pack. If a temperature below
this threshold is detected, a warning will be
generated and charging will be disabled.
Set to -41C to disable (will show as “Off”)
BMS max temp
0-101C
The maximum allowable temperature for
the battery pack. If a temperature above
this threshold is detected, a warning will be
generated and chargers and loads will both be
disabled.
Set to 101C to disable (will show as “Off”)
Charger voltage
0-70V
For CAN integration with TC Chargers only.
The maximum voltage that the BMS will instruct
the charger to reach.
Charger current
0-100A
For CAN integration with TC Chargers only.
The maximum current that the BMS will instruct
the charger to reach.
Stationary mode
No/Yes
Whether the BMS behaviour should be set for
stationary applications. Please see “Stationary
Mode” section for further explanation.
Reverse current display
No/Yes
By default, the BMS16 displays discharge amps
as positive / charge amps negative. If preferred,
you can reverse the display so that discharge
amps are negative / charge amps are positive.
Night Brightness
0-100%
Adjusts the brightness of the LCD display in
low light mode, to reduce screen glare at
night. Toggle between full brightness and night
brightness by swiping a finger up/down.
Buzzer On
Yes/No
Selects whether the Monitor should sound the
buzzer for alerts. (Safest to leave this on.)
Use Fahrenheit
Yes/No
Changes display of temperature units to
Fahrenheit instead of Celcius.
SoC Display
Percent or
Amp-Hours
The battery State of Charge value displayed on
the Monitor can either be shown as a percentage
of full charge, or as the number of amp-hours
remaining.
Stationary Mode
The BMS16 has two main modes of operation, either normal (for mobile / EV applications)
or Stationary Mode (for off grid / backup battery type applications). In normal mode, if an
under- or over-voltage is detected, the LV or HV output relay will be disabled respectively,
and will remain off until the device is either power cycled or (more commonly) they are re-
enabled whenever the device wakes from sleep.
In Stationary mode, the outputs will automatically reset if the voltage recovers sufficiently.
The BMS Hysteresis setting is used to adjust the amount that the voltage needs to recover.
For example, a hysteresis setting of 0.1V will cause the HV output to disable once the
voltage exceeds 0.1V above the programmed Max Voltage threshold, and the output will
automatically re-enable once the voltage has dropped under 0.1V below the Max Voltage
threshold.
BMS Power Consumption Protection
An inherent problem with any BMS which powers itself from the cells it is monitoring is that
the BMS itself can slowly discharge the cells, which can eventually flatten cells – particularly
if powering contactors or monitors, and no charging source is present for an extended period.
To prevent possible damage, the BMS16 is able to switch of its own power supply if any cells
get critically low (under 2.0V). If your BMS has turned off due to a critically low cell, simply
attach a charging source to the batteries then press the power button to re-enable the BMS.
